do not affect the relay.; but when a contact is made by the alarm apparatus, the current will flow through one telephone line only of the relay, and itew'ill attract its armature, closing the alarm circuit which is independent from the telephone circuit.

Referring to Figure 1, 1 and 2 designate the usual telephone conductors extending from the subscribers setto the exchange 3. The subscribers set 4 may be located whereever desired in the building, and preferably the telephone conductors should go through all the alarm `apparatuses 5, which are grounded at 6 before being connected to the subscribers set 4:. However, to reduce the cost of installation these alarinapparatuses can be installed on branch lines 12 (see Figure 2), from the telephone circuit, but `as the telephone conductors 1 and 2 can operate even if these branch lines are out of order, a special installation would be required to test these branch lines, if desired. lt is only necessary that the conductor of the telephone circuit, which is connected to the live pole of the battery at the telephone eichange be connected to the alarm apparatuses, but to safeguard against the transposition of the conductors from one pole te the other of the battery when installing or repairing the tele-` phone system, both conductors of the telephonecircuit should Vbe connected to the alarm apparatuses. f Adjacent to and ahead of theexchange on the telephone circuit is` located a relay 7, which is grounded at 8. 10 is an electrical conductor which is connected at one end to said relay 7 at 9, and at system when they alarm apparatuses 5 arev 'put in operation, thus grounding the telephonefcircuit at 6, the relay 7 is operated 'to close the contact at 9 and complete a circuit Thusv simultaneously with the operation of the alarm apparatuses 45, a signal will be given on the annuciator 11, showing immediately where the alarm has been given. l

In this system, if the telephone system is a common battery system, the relay7, in-

stead of being grounded at 8, canbe connected to the live pole ofthe battery at the eX- change and this would eliminate lthe batteryy In Figure 3 the telephone system if of the local battery type and a pole from the battery is disconnected when the telephone service is not in use, the alarm apparatuses instead of being installed and connected to the telephone conductors 1 and 2, a conductor 16a isconnected atonc end to each of the alarm apparatuses 5 and at its other end to the pole 13 of the local battery. vHowever,

-in operatiomand to maintain, however, the alarm receiving apparatus in operation. InVV some cases, this mightbe found advantageous.

and 2) extendingl from the telephone ex- To attain this object a relay 15 ish located on the alarm circuit (conductors 1 change to the ,alarm headquarters, and when lthe alarm apparatuses 5 are put in operation,

thus grounding the telephone circuit at6,the differential relay 7 operatesv closingA contact 9 and completing the circuit'betiifeen grounds i 8 and 12, and the relay 1 5 operates to close:

contact 18 and open the contacts 16 and 17 on thetelephone-V conductors `land 2'. The closing of this contact 18 completes another circuit between grounds Sand 12 which is Aaol broken by releasing of the. contact 9, througlnf the breaking ofl they contactsk 16y and 17, the

alarm receiving apparatuses are maintained in operation through theother circuit -establishedv between grounds 8 ing of the contact 18.

Referringto Figure 6 the system is slightly:

modified so thatwhen,in caseswhere several alarm apparatuses, alarm apparatuses are installed in the same building 4on the Asame telephone circuit, the.

firemen, policemen` or others arrive on the premises, where the alarm hasvbeengiven, they can locate exactly and, immediately, where the alarml has been given. To attain this object an annunciator 19 is installed'in the building, where it is most convenient, and from each alarm apparatusesv 5 are connected lines 20 which run through the annunciator v 19, before going to grounde. This annunespecially automatic ciator 19 staysv in operation till the" circuit between grounds 6 and that of thefexchange is 9 broken. Y

If a bell is desired on eachlioor, in the case of a fire alarm service for example, to'notify the people in the building incase offire, the

conductor 2O from the annunciator 19 Vmust pass through and be connected to each bell i before going to ground. p Vhat I claim as my inventionis: v

1. A signaling system comprising a transmitting circuit, ay local transmitting apparatus connected tok said circuit, anyalarm apparatus adapted to ground either limb of said circuit, a differential relay in said circuit, a

signaling circuit controlled by ,said relay and including an annunciator, means including a .relay in said signaling circuit for opening both limbs of said transmitting circuit,rand means including a shunt to said signaling circuit closed by said last mentioned relay for 5 retaining said signaling circuit closed independently of said differential relay.

2. A signaling system according to claim 1 wherein said alarm apparatus comprises an l annunciator actuated upon grounding of either limb of the transmitting circuit. l0
